Application'filed January 20,1928} Serial no. 248,200 i The presentinvention is directed to in1-' provements in traffic signals, and hasfor its primary object to provide a device of this character capable ofbeing installed upon a vehicle and conveniently operated for indi iatingto following traffic the intended courseof the Vehicle equipped with thedevice.

Another object of the invention is to provide a device of the characterspecified, so constructed that the signal will be illuminated when thearmthereof is extended and "ex-.

tinguished when the armis contracted.

Another object of the invention is to pro vide a device of thischaracter soconstructed .15 and arranged that the driver of a vehicleequipped with the device can indicate to approaching and followingtraffic, as well as to pedestrians, the intended course of the vehicle,without the necessity of extending the arm therefrom, which is nowcustomary, and while no doubt, effective, nevertheless adds to thediscomfort of the occupants of the vehicle in cold weather, since to dosonecessitates opening the window next the driver;

a While the drawings illustrate a preferred embodiment of the invention,it is to be understood that in adapting the means to meet M specificneeds and requirements, the design may be varied and such other changesin the minor details of construction may be resorted to within the scopeof the invention asclaimed, without departing from the spirit thereof.

and the merits thereof, reference is to be had to the followingdescription and the drawings hereto attached, in which,-

.1 Figure l is a fragmentary front view of a of'FigureB.

Another object of the invention is topro-- vide a device of thischaracter which is neat in appearance, effectlve in operation, and i inwhich is engaged the vehicle showing the device attached thereto andinits extended ,orjoperative position;
